XHR错误(404)加载angular2 /表格

我正在尝试在非npm模式下使用angular2(运行tomcat服务器)。服务器端使用java-spring从索引页面开始加载依赖脚本。

在我的index.html上,导入为,

<script src="https://code.angularjs.org/2.0.0-beta.9/angular2-polyfills.js"></script>
<script src="https://code.angularjs.org/tools/system.js"></script>
<script src="https://code.angularjs.org/tools/typescript.js"></script>
<script src="https://code.angularjs.org/2.0.0-beta.9/Rx.js"></script>
<script src="https://code.angularjs.org/2.0.0-beta.9/angular2.dev.js"></script>
<script src="https://code.angularjs.org/2.0.0-beta.9/http.dev.js"></script>
<script src="https://code.angularjs.org/2.0.0-beta.9/router.dev.js"></script>
<script src="https://code.angularjs.org/2.0.0-beta.9/testing.dev.js"></script>

在System.js上将打字稿配置为

 
<script>
    System.config({
        transpiler: 'typescript',
        typescriptOptions: { emitDecoratorMetadata: true },
        packages: {'app': {defaultExtension: 'ts'}}
    });
    System.import('app/main.browser')
          .then(null, console.error.bind(console));
</script>

其余的模块引用除了表单外,还可以将模块导入为

import { NgModule } from "angular2/core";
import { CommonModule } from "angular2/common";
import {
    FormsModule,
    ReactiveFormsModule
} from "angular2/forms";

在加载时间索引文件时,我得到以下异常:

angular2-polyfills.js:1243 Error: XHR error (404) loading http://localhost:8080/angular2/forms
    Error loading http://localhost:8080/angular2/forms as "angular2/forms" from http://localhost:8080/app/schema-form/schema-form.module.ts
    at o (https://code.angularjs.org/tools/system.js:4:12694)

    at Zone.run (https://code.angularjs.org/2.0.0-beta.9/angular2-polyfills.js:1243:24)
    at XMLHttpRequest.zoneBoundFn (https://code.angularjs.org/2.0.0-beta.9/angular2-polyfills.js:1220:26)

对此表示赞赏。

import { NgModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { FormsModule, ReactiveFormsModule } from '@angular/forms';

我认为你应该从@angular/core而不是angular2/core导入。现在它的@ angular / core会改变它。
